I use Skype at work,home and my iPhone.
Skype Wifi is another application. What Skype have done is come to an arrangement with many ISP's around the world who have Hotspots. This App finds one of these hotspots and when the new App is used to make a call a charge occurs that includes the hotspot use.
Seems useful when no free Wifi is available.
Skype WiFi - Wireless Internet Access from WiFi Hotspots - Skype
I checked the price of calls and in Hong Kong it is approx 10 to 15c/min depending on which hotspot is found.
Have tried to test the app out at home but could not detect any of their hot spots listed. (Maybe I don't live near a hot spot)
